Different from Elaines Celadon(?) or is it just different batch #'s

BUT agin - barium has entirely replaced the Calcium that celadons
normally use. Here are the other "normal" recipes:

(Also I got lots of hits typing "blue iron oxide" into google. So it
seems the pigment called "ultramarine blue" is an iron blue - maybe -
MAYBE blue iron oxide can be added to the electric kiln version in
place of other iron pigments)

These glazes show their truest color on porcelain. The blue celadons
are at their very best on porcelain bodies that are very low in
titanium. If you are using a claybody that will muddy the blue, you
might try some porcelain slips. The glaze needs to be applied thick
for good color. There is a small amount of iron in the glaze for color
and it's easy to lose the color if there isn't enough depth. It's
always a good idea to do several test tiles with several thicknesses
of glaze on each one. You are looking for the effect that YOU want.
After wet mixing, screen the glaze about 3 times thru at least a 100
mesh. 120 mesh is better. You want to disperse the iron so you get a
nice sky blue with no iron spots, unless you want iron spots. I ball
mill the glaze for an hour and then screen once thru a 100 mesh. The
milling does a swell job of dispersing the iron. When I do tests I
just screen 3 times and it works ok. If you want to try custer
feldspar instead of g-200 it should work OK. I calculated the glaze
with both spars and they are close enough with regard to the critical
oxide, which is potassium. For blue celadons the potassium in the
seger formula should be at about 0,3. Any less and the glaze is less
blue. If barium makes you nervous, you can leave it out but the glaze
won't be as blue and the color will be slightly harder looking. This
is a pretty durable glaze and the barium is low enough so I wouldn't
expect any serious leaching providing the glaze was fired properly and
brought to maturity. I fire these pots in a 12 hour cycle. Gas kiln
fired with propane. I start reduction at cone 06 and set the oxyprobe
at 0.7. I leave the damper at the 0.7 setting until cone 5 and then I
open it a bit to get 0,5 on the oxyprobe. I let the kiln climb until
cone 8 is at about 2 O'Clock and then I set the damper to get an
oxyprobe reading of 0.65 and I hold this until cone 10 is down. I
usually take 2.5 to 3 hours from cone 8 softening until cone 10 is
down. I cut the gas and hold the kiln at top temp for about an hour
with an oxyprobe reading of 0.6. After the soak I shut the kiln down
and close the damper and all ports. I open it about 36 hrs later and
hope for the best! :>) A further thing about the soak. I actually let
the kiln drop slightly during the hour soak. Usually to about cone 9.

I like the idea of lower temperature celadons. Has anyone had any experience
wiht these recipes?
Does anyone know what a substitution would be for the Pike's clay in the
Leach recipe? Maybe a type of ball clay since china clay is listed
separately?

I see you include some Chuns. Here is the one I use. The
interesting thing is that chuns looks something like a nezumi shino I
've seen at the Mingeikan.

Tichane's book insists that Lung-ch'uan is a lower temp longer firing
with slow cool in reduction. I haven't tried them. My job here is to
cut and paste. I used to earn my bread doing layout, paste-up, camera,
stripping (no, not that kind), and plate making for photo offset. So I
have that kind of habit.

Pikes Clay is a high silica ball clay - As I remember the Kentucky
Tennessee company lists several on their site - http://www.ballclay.com/

Click on "ball Clay" near the top of that page - Kentucky stone was
recommended to me at Georgies - I see it is in the list

here is a great pic of variously colored iron oxides:
http://tongchem.en.alibaba.com/product/50047239/50215229/Pigments/Iron_Oxide_Pigments.html
my question here is to what degree will these colors be maintained in
an electric kiln fired to around cone 6-8?

Chuns often have purple or red splashes on them. It comes from copper slip/

Related to copper, Seiji is Japanese for Celadon. The Nuka green
is called Seiji Nuka. Mashiko potters were trying to copy celadon
by putting copper in their rice hull ash glaze. Up north, they have
a bluer glaze like it, but it is made from a local stone. I wish I
had an analysis of it!

I should have been more clear. How do make copper slip? I have used Pete's

I just use my usual slip. Often I use Continental Clay's Super
White (they sell it dry.) Or, you can make it from the trimmings of
the body you are using and you will be assured a good fit.

Thanks Lee - I have collected your recipe related posts over the years
- however somewhat unsystematically - I'm trying to figure out what my
system should be. Alphabetical? By category?
by cone? What is the proper Linneaus system for glazes/slips/enogbes/
clays anyway?
By the way, which ones are Chuns as you see it? I had some nezumi
shinos in my hot little hands down at the Freer; also really red old
shinos too

Folks: Celadons are through and through green, blue, white, (yellow,)
etc. Chuns are optical blue, if chipped, the illusion vanishes. This
is due to minute bubbles in the super saturated solution refracting
into a bluish color. The copper splash produces a violet or purple
area. Tichane includes Chuns as Celadons; however they are really
different animals

I am going to fire some cone 6 wares to bisque tomorrow. I have a
number of glazes lined up including
AG 19 Issenburgs/Ashpot
Malmgren's White Breaking Brown
Andy's Handful of Earth
Schweiger's Liner
Kemp's 111
Hambone's 123
& plus trying to figure out what to do with the weathered andusite
Hank & I dug up in the Oregon mountains...
H A M

p.s. I was really impressed by a Japanese ultra-contemporary
sculptural work I saw at the San Francisco museum once - sort of a
triangular girder shape in blue green celadon - it seemed to be
transparent - as though you could see right through it, although it
was 6 - 12 " thick. Very close approximation to a certain type of jade
- I didn't get the artists name because back then I was absorbed into
Shigaraki, Tamba, Bizen wares and took no notes. Still, the illusion
was indelibly etched into my mind...

Recipe calls for 3%. Because it is mostly feldspar, it dries
quickly and shows runs easily. When thick, looks like big quartz
crystals. Only sky blue on porcelain. On stoneware, it looks like
some nezumi/mouse shinos I have seen.

I don't have mine in any order, but I do have them in
multiple notebooks.

There are a variety of nezumi shinos. Some are smooth like
the white to red ones we know, but some are transparent and show
distinctive crazing, like thick Chuns do. There is a bowl at the
Mingeikan with a white inlayed Yanagi/willow decoration. I have a
photo somewhere. It is in Sander's book on Japanese ceramics (I
didn't realize it until I saw the actual pot at the Mingeikan.)

There are a large variety of shinos. The primary
differences, I think are due to the place in the kiln they are placed.
But seeing the willow nezumi bowl, I think the actual make up of the
shinos vary too.

I scanned the pot I talked about above from Sander's book and put it up here:
